The inner hole of pin pressing plate is the cylindrical cavity cooperated with pinion frame small end, the diameter m1 and row of cylindrical cavity
The relationship for the smallest circle size m3 that gear rack small end outside diameter M1 and multiple copper sheets are constituted are as follows: 1 > m1-M1 > 0.5,
M1-m3>0.5。
It is furnished with multiple spring copper sheets in the inner hole of pin pressing plate, lower end and the pin pressing plate inner hole wall of spring copper sheet are fixed,
Pinion frame small end is put into pin pressing plate inner hole, is embedded in pin pressing plate under the supporting role of spring pressuring plate.
Pin hole depth on pin seat is that can guarantee the consistency of pin ride out H.
Pinhole on pin seat is multiple groups, and every group of pinhole is distributed on the same circumference, and multiple groups pinhole forms multiple
Concentric circles.
A kind of application method of pinion frame class product press fitting pin frock clamp of the present invention, comprising the following steps:
1) hole location of 2 push-piece stroma 4 of pin is placed in corresponding pinhole first；
2) pinion frame is placed above pin 2；
3) after placing pin pressing plate 3 above pinion frame 1, load force protection is uniformly transferred by pin pressing plate
Pinion frame；
4) load is continued to pin pressing plate 3, completely attaches to 1 large end face of pinion frame and 4 upper surface of pin seat；
5) pin pressing plate 3 is removed, takes out the pinion frame 1 of press fitting finished product, one time pin press fitting process finishes.
Step 2) specifically:
201) pinion frame small end is put among multiple spring copper sheets of pin pressing plate inner hole；
202) pinion frame is integrally placed into above pin with pin pressing plate is entered.
The invention has the following beneficial effects and advantage:
1. pin positioning is difficult when the present invention solves pinion frame press fitting, is not easy with pinion frame hole location to just etc. asking
Topic, structure is simple, and it is convenient to operate, and examines the outer diameter of pin during press fitting indirectly.
2. the process using pressing clamp of the present invention press fitting pin belongs to a kind of opposition thinking, i.e., pin is placed first,
In the case that pin is fixed, pinion frame is placed to positive with pin, then place pin pressing plate, pin pressing plate is applied and is pressed
Pin and pinion frame are finally press fit together by power, are arranged so that pin simplicity, can also be excluded outer diameter pin bigger than normal
Son, and be easy to pin and pinion frame circular hole to just, press fitting.

Specific embodiment
The present invention is further elaborated with reference to the accompanying drawings of the specification.
A kind of pinion frame class product of the present invention is pressed pin frock clamp, including pin pressing plate 3 and 4 liang of pin seat
Part, wherein pin seat 4 is equipped with pinhole, and hole location is identical as 1 hole location of pinion frame, and pinhole internal diameter is than pin 2
Big 0.00~the 0.02mm of outer diameter；Pin pressing plate 3 is a pressing plate with inner hole, and it is small that bore depth is greater than pinion frame 1
End surface thickness, 2 pressing plate of pin cover entire 1 large end face of pinion frame.
The inner hole of pin pressing plate 3 is the cylindrical cavity cooperated with 1 small end of pinion frame, the diameter m1 of cylindrical cavity and
The relationship for the smallest circle size m3 that 1 small end outside diameter M1 of pinion frame and four copper sheets are constituted are as follows: 1 > m1-M1 >
0.5, M1-m3 > 0.5 means, multiple spring copper sheets constitute the smallest round size m3 and are less than 1 small end outside diameter of pinion frame
M1, by the elastic reaction of spring copper sheet 7, can clamp pinion frame after such 1 small end of pinion frame is put into.
Pin hole depth on pin seat 4 is that can guarantee the consistency of pin ride out H.
In Figure 1A~1C, d2 is pinhole internal diameter, and M1 is pinion frame large end face diameter, and M2 is pinion frame small end
Face diameter, N are pinion frame small end face thickness；In Fig. 2, d1 is pin outer diameter, and H is pin ride out；In Fig. 3 A, n is
The bore depth of pin pressing plate；In Fig. 3 B, m1 is the diameter of bore of pin pressing plate, and m2 is the outside diameter of pin pressing plate, pin
The depth of pressing plate is identical as pinion frame big end thickness, K1 > K2, and mark pinion frame big end thickness K1 is greater than pin pressing plate
Depth K2, the pressing force that pinion frame 1 can be between the two by pin pressing plate and pin seat when press fitting, if but K1 < K2, apply
After load, pinion frame and pin seat have larger gap, are not able to satisfy the requirement of pin ride out H size), prevent pressure
When excessive, 1 stress of pinion frame is excessive to be caused to deform or crack.
In the present embodiment, the bore depth n > pinion frame small end face thickness N of pin pressing plate makes the interior of pin pressing plate 3
The small end face contact of Kong Buyu pinion frame 1；The diameter of bore m1- pinion frame large end face diameter M1 of 1 > pin pressing plate
> 0.5, the small outer circle of pinion frame can be put into pin pressing plate inner hole, but should not be too large, and mutual play is avoided to lead to planet tooth
Wheel carrier end face unbalance stress, also unsuitable too small, inconvenience uses；The outside diameter m2- pinion frame small end of 2 > pin pressing plates
Face diameter M2 > 0, pin pressing plate cover entire pinion frame end face, guarantee pinion frame uniform stressed.Meanwhile inner hole is matched
There are four spring copper sheet 7, root and 3 spot welding of pin pressing plate of spring copper sheet 7 are fixed, and 1 small end of pinion frame can be put into pin
In 3 inner hole of pressing plate, by the supporting role of spring copper sheet 7, pinion frame 1 can be embedded in pin pressing plate 3 and whole therewith
It vertically moves, pinion frame 1 is not fallen, and planetary gear 1 and pin 2 is facilitated to place to positive.
Fig. 4 A~4B show pin seat 4, and hole location is identical as pinion frame hole location, wherein pinhole internal diameter d2 size ratio
1 size big 0 to 0.02 of pin outside diameter d, can be put into the pin of qualified size, can also exclude oversized pin, guarantee suitable
Pinion frame will not crack since magnitude of interference is big after benefit indentation pin.
Pinhole on pin seat is multiple groups, and every group of pinhole is distributed on the same circumference, and multiple groups pinhole forms multiple
Concentric circles.In the present embodiment, on same construction circle, by 3 it is heavy be used as one group, hole and 5 counterbores as another warp and, two groups of counterbores
Structure fabrication together, reduces mold manufacture, saves mold materials.
Shown in Fig. 5, for the process schematic for using this tooling pressing, operating process is as follows:
1) hole location of 2 push-piece stroma 4 of pin is placed in corresponding pinhole first.
2) pinion frame 1 is placed above pin 2, because there is the arc size of R0.5 at 2 both ends of pin, is on the one hand risen
Guiding role, is aligned pinion frame hole location with pin 2, is on the one hand conducive to the pin that pin 2 is inlaid into pinion frame 1
In sub-aperture；
This step is completed in two steps:
201) pinion frame small end is put among multiple spring copper sheets of pin pressing plate inner hole；
202) pinion frame is integrally placed into above pin with pin pressing plate is entered.
Since there is the arc size of R0.5 at pin both ends, on the one hand play the guiding role, easily make pinion frame hole location with
Pin alignment, is on the one hand conducive to pin and is inlaid into pinion frame aperture.
3) after placing pin pressing plate 3 above pinion frame 1, load force is uniformly transferred by pin pressing plate, is had
Effect protection pinion frame, prevents from weighing pinion frame wounded；
4) load is continued to pin pressing plate 3, completely attaches to 1 large end face of pinion frame and 4 upper surface of pin seat；
5) pin pressing plate 3 is removed, takes out the pinion frame 1 of press fitting finished product, one time pin press fitting process finishes.
